T 0 all 'whom z'z may concern Be it known that I, PERCIVAL WELL, acitizen'of the United States, and resident of Philadelphia, PhiladelphiaCounty, State of Pennsylvania, have invented certain new and usefulImprovements in Bearings and Supports Therefor, of which the followingis a specification.

This invention relates' to bearings and supports therefor, andparticularly to such bearings and supports as are employed in clutchesfor motor vehicles.

The invention is illustrated herein as applied to the rear clutchbearing of a combined-motor and Clutch casing.

An object of the present invention is to produce an anti-friction orball bearing adapted to take. radial and double thrust loads combinedwith a Container of such form that it will hold the bearings in properrelation to the shaft which the bearings support, while at the same timebeing lirmly .clamped to a supporting member.

Another object of the invention is Vto produce such a bearingandcontainer as abovev described, while at the same time providing meansfor easily' and quickly assembling and removing the bearings.

Referring to the drawings: Figure .1 is 'a vertical longitudinalsectional View of the rear end of a motor crank case and the integralextension thereof which supports a clutch, the clutch and iiy-wheel ofthe motor beingl shown in elevation; Fig. 2 is a section on the line 2-2of Fig. l; Figs.v 3 and 4 areI longitudinal, sectional views of theradial and thrust "bearings and their container showing the bearings inprocess ofassembling in the container; Fig. 5 is a perspective view ofthe container.y

Heretoforeywhere a container has beenprovided fora thrust bearing thatis adapted to take thrust in both directions the container either hasbeen split- .longitudinally in order to take the thrust disks and ballretainer or ithasbeen provided with'a ring screwed'into'the interior ofthe container for securing the 'thrust bearing between it and theinterior flange. The first of these constructions is @objectionable inthat the two parts of the container', in being clamped to a support aresometimes shifted relative to each other making an out-of-round sleeve;whilet-he latter of said constructions-is objectionable in that H,BREAK-l the thrust in one direction is necessarily andthe double thrustbearing is inserted between two separated interior flanges through atransverse slot ,formed in the container. The mannerof assemblingtheyparts of the bearings will be hereinafter described. Thebearings andjcontainer above briefly referred toy are show ir as forming the rea-rclutchbearing' of'a motor and c luteh'vcasing, and-the' invention as'soemployed will now be describedin detail.

Referring tothe drawings, 10 represents the rear port-ion of the crankcase'of an linte:nal lcombustion motor 'adapted for motor vehicle use,and 11 is the bottonrcover of this crankcase. I f

12 is themotor crank shaft, and'13 isthe flywheel of the motor uponwhich is secured the clutch drum 14.

The clutch may be of any desired type,-

variety. `1 The inner or movable part of the 'clutchV is 'shown at 15and it is operated axially "by the Collar V16,'yoke 17 pivoted at 18,linkv 19 and pedal Vlever 2O pivoted' at 21 on `the casing22, :whichcasingl is formed as an extension vof the `motor crank case 10, andtogether with the topV Cover 23 and lower cover'24 forms a housing forthe clutch and flywheel. vThe clutch'- shaft. 25 is lformed in two partsjoined by the connecting block 26 and bolts 27, the block being insertedbetween'these two parts to separateythem afterlthe-'clutch lis insertedin the casing. `By the removal f this block' the forward partof the4clutclrshaft may be 'moved rearwardly .with the clutch and the `latter"removed from` the casing. The clutch shaftV 25 is supported 'in aradial bearin 28 and a thrust bearing`29,`5\vhi`cl1 latter'-isof'thetype that takes thrust in both directions. "The inner racevofth'era-y dial bearing 28 issecured to the shaft 25 abuts againstanother shoulder on the shaft 25, --The yoke 31 above referred to issecured to the shaft 25 by a key as shown and by a lock screw 35. y

The rear end of the casin 22 is formed with an opening through w ich theshaft Figsi and 2.

` the upper and lower parts ofthe casing 22 cant in the bearings.

it can have no movement axially. This, of

course, is for the purpose of taking the thrust of the shaft -25 in bothdirections. This container 37 is provided interiorly with a double ange39, which when assembled immediately surrounds the ringI 34 on the shaft25, and suitable packing material may be placed in the groove 40 formedin thisv Harige 39l for the purpose of retaining lubriiange 39 in thecontainer is a flange 41 and between these flanges is an annular, spaceadapted to contain the three parts of the thrust bearing 29, whichthrust bearing is adapted to be assembled in said space, one of itsparts at a time, through a slot 42 cnt transversely in the container 37approximately midway between the Aflanges 39 and 41. The total lengthfof this slot is approxi'- mately the interior diameter ofthe container37 between the flanges 39 and 41,

The thrust bearing 29 is composed of two thrust disks 43 and a ballretaining disk 44 adapted to be assembled between the disks 43. Thethrust disks 43 are preferably about as thick as lthe diameter of theballs 45 in the ball retainer 44, the slot 42 is approximately the widthof the diameter of said balls, and the space between the flanges 39 and41 is adapted to take the complete thrust bearing. IVith theseproportions it will be evident upon reference to the drawings, andAparticularly to Figs. 3 and 4, that ene of the disks 43 may be insertedthrough the slot 42and positioned as shown in Fig. 3, the second disk 43may then be positioned as shown in Fig. 4, and the ball retaining diskmay' then be' inserted through the slot 42 between the two disks 43. Ifthe container 37 is then clamped between the upper and lower parts ofthe casing 22, there is up er and Separated from the` of course nochance for the various pints ofthe thrust bearing to drop out.

The radial bearing 281`sof the usual-ba'll type, having inner and outerrace 4rings with balls between them and the container 37 is for edinteriorly at one end to take they outer race of said bearing 28, thebearing being assembled in the container as shown in Figs. 3 and 4.

The bearings may lubricated by means of a grease or oil cup 46 arrangedin the casing 22 directly above the slot 42 so that grease or oil fromthis cup will reach the bearings through said slot. Having thusdescribed my invention, what I claim is:

l. The coir'bination with a thrust bearing comprising a ball retainingdiskwith balls thereinand a thrust disk, of a'container for i saidbearing comprising a sleeve having a' transverse entrance slot thereinfor said disks.

2. The combination with a thrust bearing comprising a ball retainingdisk with balls therein and a thrust disk, of acontainer for saidbearingcomprising a sleeve havin a pair of separated internal anges and atransverse slot between the flanges for the entrance of said disks.

The combination with a thrust bearing comprising a ball retaining diskwith balls therein and a pair of thrust disks, of a container for saidbearing comprising a sleeve having separated internal flanges and atransverse slot midway between said anges adapted to permit the entrance4singly of said disks.

4. The combination with a bearing, of a container therefor comprising asleeve having a transverse entrance slotfor said bearing, and a two-partsupport for said container adapted t0 be secured together around rthecontainer.

5. The combination with a bearing, of a container therefor comprising asleeve having a transverse entrance slot for said beaiing, a-support forsaid container surrounding the latter, and a grease cup in 'said supportadapted to deliver lubricant to said hearing through said entrance slot.

In testimony whereof I affix my signa ture in the presence of twowitnesses.
